Mosquito Gear: What Works and What to Skip

One thing first. Gear handles the mosquitoes that are already flying. The weekly container check handles the ones that have not hatched yet, and it costs nothing. If you have not done it, start with the ten-minute weekly yard check and come back here.

No product on this page acts on any virus. What good gear does is lower the number of bites you take, and fewer bites means fewer chances of exposure.

1. Repellent on your skin

This is the piece with the clearest public guidance. The CDC's mosquito bite page (updated August 28, 2024) lists six EPA-registered active ingredients:

• DEET
• Picaridin (also sold as icaridin)
• IR3535
• Oil of lemon eucalyptus (OLE)
• Para-menthane-diol (PMD)
• 2-undecanone

Look for one of those names in the active ingredient line on the back of the bottle. The brand on the front matters less than that line. If you want help choosing, the EPA runs a free online tool for finding a registered repellent that fits your needs.

For children, the CDC is specific:

• Do not use products containing OLE or PMD on children under 3 years old.
• An adult puts repellent on their own hands first, then applies it to the child's face.
• Never put it on a child's hands, eyes, mouth, cuts, or irritated skin.

Reapply on the label's schedule, not on a hunch. Every registered repellent carries directions for how often to reapply. If you sweat, swim, or towel off, check what the label says. If the label and a friend's advice disagree, the label wins.

"Natural" is not a safety category. Read the label for age and use restrictions. Oil of lemon eucalyptus is plant-based and on the CDC list; a plant oil that is not one of the six is not on it.

2. Permethrin-treated clothing and gear

Permethrin goes on fabric, not on you. The CDC says it plainly: "Do not use permethrin products directly on skin." You can buy clothing that comes pre-treated, or treat your own clothing, shoes, and gear by following the product label exactly.

This suits the gardener, the runner, the parent at evening practice, and anyone who works outside. Pair it with skin repellent on whatever the fabric does not cover.

3. Physical barriers: screens, fans, sleeves

These are not exciting, and they are some of the most useful things you can own.

1. Screens on every window and door you open. Walk the house and look for tears, gaps at the frame, and the sliding door that never quite closes. Patch kits are easy to find and the fix takes minutes.
2. A fan on the patio. A steady breeze from a box or pedestal fan may make it harder for mosquitoes to land on you. Point it across where people sit, at ankle and leg height. It is a modest help, not a force field.
3. Long sleeves and long pants. Loose fabric is easier to wear in heat. Socks matter too; ankles are easy to miss. If you are getting bitten in the afternoon, read our guide to the daytime-biting mosquito.

4. Larvicide dunks for water you cannot dump

Tip and scrub what you can. For water you cannot empty, such as a rain barrel, an ornamental pond, or a fountain basin, look for an EPA-registered product made with Bti (Bacillus thuringiensis subsp. israelensis), sold as dunks or granules. The EPA (updated June 2, 2026) describes Bti as a naturally occurring soil bacterium whose toxins affect only the larvae of mosquitoes, black flies, and fungus gnats.

Follow the label for where and how to use it, and do not improvise. If you have a pond, ask your local vector control program about mosquitofish first. Many programs give them away free.

5. Spatial repellent devices

These are clip-on, tabletop, or plug-in devices that release a repellent into the air around you. Products vary widely in what they claim, so check that the one you pick is EPA-registered. The label is the ceiling. Read the coverage area, the run time, and the indoor or outdoor restrictions there, not on the box art or the ad. If the label does not say it, do not assume it.

6. Traps: be honest with yourself

Backyard mosquito traps are popular, but a full catch bag does not show that fewer mosquitoes are biting you, and none of the sources we cite recommends a trap for that. Where a trap can earn its place is monitoring: it tells you whether mosquitoes are around and roughly when. Vector control programs collect mosquito samples for the same kind of surveillance. Treat a trap as an extra, not as your main line, and keep doing the weekly check.

What to skip

• Ultrasonic devices. These claim to drive mosquitoes away with high-pitched sound. None of the sources we cite recommends them, and none of the six CDC-listed active ingredients works by sound.
• Repellent wristbands. Repellent works on the skin it covers. A band on one wrist leaves the rest of you open, especially your ankles.
• Bug zappers. A zapper kills whatever flies into its light. The bite guidance cited here relies on repellent, covered skin, and emptying standing water instead.

Do not mix pesticide instructions

Each product's label is written for that product alone. Do not borrow directions from one product to use another, and do not combine products to make something stronger. For spraying across a whole yard, the answer is a licensed applicator, not a store-bought sprayer and a guess.

What the county does vs what you do

Your local vector control program already does a lot of this work, and many will come look at your property for free if you ask. Credit them first. Here is how the gear question splits.
